Photographs and records of basidiomata were obtained in the field. Materials and methods Morphological studies The aims were to 1) evaluate the phylogenetic relationships within the genus 2) redefine the characteristics of Aureoboletus 3) elucidate the species diversity of Aureoboletus in China 4) describe the newly discovered species. In this study, the species richness and phylogenetic relationships were re-evaluated, based on detailed morphological observations and a four-gene phylogenetic inference. Numerous Aureoboletus specimens have been recently obtained in China, increasing the species diversity of Aureoboletus. Curtis) Singer) were transferred into the genus Aureoboletus, based on both morphological and molecular data ( Halling et al. Gilbert and Pulveroboletus auriflammeus (Berk. 2014) Boletellus projectellus (Murrill) Singer, B. Zang, originally described in south-western China, was proven to be a synonym of Aureoboletus ( Zang 1992 Wu et al. ( Binder 1999 Binder and Hibbett 2006 Nuhn et al. Aureoboletus was strongly supported as a genus in the Boletaceae, subfamily Xerocomoideae and has been shown to be closely related to Boletellus, Hemileccinum Šutara, Heimioporus E. Recently, broad-scale molecular phylogenetic studies have been used to investigate phylogenetic relationships amongst the genera and species in Boletes. A world-wide survey of the genus, based on morphological characteristics, was conducted and a key was designed to aid in the identification of 11 global Aureoboletus species ( Klofac 2010). 2000) However, Aureoboletus was accepted as an independent genus by other mycologists and the features of the genus were redefined ( Watling 1965 Watling 2008 Hongo 1973 Zang 1993 Šutara 2008 Klofac 2010). 2000 Šutara 2005) and species with viscid basidiomata and vivid yellow hymenophores were variously placed in genera Boletellus Murrill, Boletus L., Pulveroboletus and Xerocomus Quél. For a long time, the genus Aureoboletus was not accepted as an independent genus by some mycologists ( Smith and Thiers 1971 Corner 1972 Singer 1986 Both 1993 Bessette et al. Later, Auripori species were transferred to the genus Pulveroboletus Murrill ( Singer 1947). Xerocomus section Auripori Singer (1942) was established to accommodate Aureoboletus-like taxa. The establishment and acceptance of the genus Aureoboletus has a long history. 2003 Klofac 2010 Shi and Liu 2013 Halling et al. Interestingly, they are strongly implicated as symbionts with an array of ectotrophic plants of the Fagaceae and Pinaceae families ( Pouzar 1957 Yang et al. Aureoboletus species can be found in tropical, subtropical and temperate regions of different continents, but most known species appear to exist in Asia and North America. To date, 35 species have been described worldwide, 15 of which were originally described in China ( Patouillard 1895 Shi and Liu 2013 Zhang et al. It was characterised by its slimy basidiomata, glabrous to subglabrous pileus and golden yellow hymenophore unchanging when dry ( Quélet 1884 Saccardo 1888 Pouzar 1957). Aureoboletus Pouzar was circumscribed in 1957, based on the type species A.
